GQF-E expansion joints are widely used in buildings that require expansion such as highways, bridges, airports and subway stations. The advantages of modular expansion joints include stable structure, strong load-bearing capacity, ability to withstand various forms of deformation and extrusion, and adaptability to the needs of different environments and climates.
Deformation performance requirements of telescopic devices
The expansion joint device adapts to meet the needs of the bridge’s vertical and horizontalVertical three-dimensional deformation requirements, the deformation performance of the telescopic device meets the requirements in the table below. When the deformation of the bridge causes significant lateral and vertical dislocation of the telescopic device, the plane angle requirements and vertical angle requirements of the telescopic device are determined through special research, and the deformation performance is tested.
GQF-EThe type isANDSection steel telescopic device, its main specifications are:E40、E60、E80, respectively applicable to the expansion and contraction amounts of0~40mm、0~60mm、0~80mmbridge use.
The GQF-E expansion joint product is used for expansion joint processing of building structures. It is mainly used to withstand the stress and deformation caused by the expansion and contraction deformation of the building due to temperature, humidity, settlement and other reasons. Its main function is to protect the structure and appearance of the building, reduce stress concentration, and prevent wall cracking and damage as well as ground cracks.
The product installation steps are generally carried out in the following order:
-
Determine the installation location: Determine the installation location of the expansion joint according to the design of the building and actual needs. It is usually necessary to select an appropriate location for installation between the walls, ground and other structures of the building.
-
Prepare installation materials: Prepare required expansion joint materials, including expansion joint strips, fixing clamps, sealing materials, etc.
-
Clean the installation surface: Clean the relevant structural surfaces around the installation location to ensure that the installation surface is flat and clean.
-
Install the fixing clamp: According to the design requirements, select the appropriate fixing clamp and fix it on the installation surface.
-
Cut the expansion joints: Cut the expansion joints according to the size requirements of the installation location to ensure that the length and width are appropriate.
-
Install the expansion joint strips: Install the cut expansion joint strips onto the fixing clamps and make sure they are firmly and tightly fixed.
-
Seal the gap: Use appropriate sealing materials to seal the periphery of the expansion joint to ensure the waterproof and sealing performance of the expansion joint.
-
Improve detail processing: Perform detailed processing on the installed expansion joints, including trimming the joints, finishing the appearance, etc.

Steel shuttering is a material used to cover expansion joints. By laying over the expansion joints, it can protect the expansion joints. Steel shutters have excellent wear resistance and corrosion resistance, long service life, and are easy to clean and maintain. It is suitable for various buildings, such as indoor floors, exterior walls, ceilings and various ground projects.
Modular expansion joints are a design that allows expansion and contraction by connecting multiple modules.GQF-E expansion joint type, GQF-Z expansion joint type, GQF-C expansion joint type and GQF-F expansion joint type are common modular expansion joints. Their differences lie in the installation method, appearance design, load-bearing capacity and other characteristics. They are widely used in buildings that need to be telescopic, such as highways, bridges, airports and subway stations. The advantages of modular expansion joints include stable structure, strong load-bearing capacity, ability to withstand various forms of deformation and extrusion, and adaptability to the needs of different environments and climates.
SF comb plate expansion joints use comb-shaped metal plates to connect to achieve expansion and contraction functions. SF comb plate expansion joints have large load capacity and horizontal displacement capacity, can withstand the traffic pressure of vehicles and pedestrians, and are suitable for indoor and outdoor places in high-rise buildings, such as underground garages, subway stations, shopping malls, etc. Its advantage is that it has a stable structure, can withstand large pressure and displacement, and has good anti-slip effect.
TST filled expansion joints use filling materials, such as rubber, etc., to achieve expansion and contraction functions. TST filled expansion joints can effectively prevent water, dust, etc. from entering the interior of the building, and can absorb vibration and deformation caused by earthquakes, temperature changes, settlement and other factors. TST filled expansion joints are suitable for indoor places, such as office buildings, hospitals, gymnasiums, etc. Its advantages include good sealing, excellent waterproofing effect, and good earthquake resistance.
HZF expansion joint is a wall expansion joint that realizes expansion and contraction function according to the changes of building structure. HZF expansion joints can expand and contract with temperature changes and building deformation, and have good sealing and waterproof properties. It is suitable for places such as high-rise buildings, hotels and commercial buildings. The advantage of HZF expansion joints is that they can adapt to the deformation of the building, provide good earthquake resistance, and can effectively prevent water, dust, etc. from entering the interior of the building.
Summary: Steel shutters are suitable for covering and protecting expansion joints; modular expansion joints have different models and characteristics and are suitable for highways, bridges, airports, etc.;SF comb plate expansion joints are suitable for underground garages, subway stations, etc.; TST filled expansion joints are suitable for indoor places; HZF expansion joints are suitable for high-rise buildings, hotels, etc. These products offer strength, durability, ease of installation, and can be customized to the building’s needs. They are able to cope with the challenges posed by different environments and external factors while maintaining structural safety.
